Hijab, which means covering the body from non-mahrams, is one of the essential laws of Islam. There is Hijab in other divine religions, including Zoroastrianism, Judaism, and Christianity, with some differences.

Quran and its provisions are the basis of unity among all Muslims. Muslim women also have a very influential role in creating and promoting the unity because they can easily affect their children and their husbands.
